Load it…then use your favorite V4 skin and then in the Surfaces tab, change the Diffuse Color to something ‘blueish’ for each of the skin areas and save it as a preset.
Poser materials not working correctly should not be a ‘show stopper’...it’s always been that way and probably always will be. There’s tons of stuff (basically everything except dynamic hair and clothes) that may not have ‘proper’ materials for DS, but otherwise works, perfectly.
